Tires OEM Chevrolet or BRIDGESTONE

I found the Bridgestone tire to be alittle more forgiving and last longer. The grip on these tires are both amazing and hard to tell them apart on snow and ice.

After taking the WS80's out in some snow and firm hardpack, I am very impressed.

I do like the PSS much more than my old Bridgestones. They are so much quieter. I'm sure I'll very much enjoy the next 10-12K miles I get out of them.

I use Blizzak WS80's and a couple 50lb sandbags in the trunk. No issues as long as there isn't a shit ton of snow. I still avoid all steep hills.

I have blizzaks and Mrs. Krieg had ice guards on her last car. Both are excellent snow tires, and I never noticed a difference in the wet.

I'm a big fan of the Bridgestone Blizzak tires (in your case, WS80).

As a counterpoint to the Michelin PSS, I have Bridgestone S04 Pole Position tires and have been very happy with them. Dry and wet performance has been excellent.

They're sort of expensive I think, but the Bridgestone Battlax S20 is really nice in the wet. I had Pirelli Diablo Corsas and moved away from them specifically because of their poor performance in the wet.

I had Ecopias (EDIT: EL-400s) on my Mazda3. They would not die. At like 90k miles I replaced them because they had gotten hard and the snow traction declined... they still had a decent amount of tread left.

The factory tires on my 335i are Japanese made Bridgestone RE050 Run-flats. They suck, harsh ride, low tire life, loud, and most of all one small pot-hole and you got an instant sidewall bubble.
